Systems of Equations: Substitution Method #1 (2/27)

Solve the following by using the substitution method.

Remember solve for both “x” and “y”

1) 2x + 8y = 20 2) x = 5

y = 2 2x + y = 10

3) 5x – 2y = 3 4) 2y + x = -15

y = 2x x = 3y

5) 4x + 7y = 19 6) y = 6x + 11

y = x + 9 2y – 4x = 14

7) 2x – 8y = 6 8) x = 2y – 1

y = -7 – x 3x – 2y = -3
